The Unexpected Rise of a Climate Commentator
When Jack Schlossberg speaks about hurricanes, people listen. Not just because of his famous surname — his grandfather was President John F. Kennedy — but because the 31-year-old Harvard-trained lawyer and former journalist has become one of the most quoted figures connecting individual storm events to long-term climate trends. In the past three months alone, Schlossberg has posted eight analyses on social media that have been shared by over 200,000 accounts, many of them targeting specific Hurricane and wildfire events.
His latest thread, published on February 12, 2025, focused on the alarming sea surface temperature anomalies in the Gulf of Mexico. Schlossberg noted that parts of the Gulf were running 3.5°C above the 1991-2020 baseline. “That’s not just a number. That’s fuel for tropical cyclones,” he wrote. The post accumulated 47,000 retweets within 48 hours.
“Schlossberg brings a unique blend of legal analysis and data fluency to weather discussions. He doesn’t just say ‘the storm was worse because of climate change.’ He shows the specific measurements — the ACE Index jumps, the intensification rates, the moisture content percentages. That resonates with our audience.”
From Kennedy Legacy to Weather Data Nexus
Schlossberg’s pivot to weather commentary is not accidental. After graduating from Harvard Law School and Harvard Business School in 2022, he worked briefly at a climate-focused think tank. He then launched a newsletter, “The Reckoning,” which now has 340,000 subscribers. In each issue, he selects one or two extreme weather events and dissects them using data from NOAA, ECMWF, and local meteorological offices.
On December 5, 2024, he examined the rapid intensification of Hurricane Lorenzo in the eastern Atlantic. Using graphs from the National Hurricane Center, he showed that the storm’s pressure dropped 54 millibars in 18 hours. “That rate is historically significant. Only 7 storms in the satellite era (since 1966) have matched or exceeded that,” Schlossberg wrote. He then correlated that intensification with sea surface temperatures that were 2.1°C above normal along the storm’s path.
His approach has drawn both praise and criticism. Some meteorologists argue that he oversimplifies complex dynamics. “Single-storm attribution is still tricky,” says Dr. Mark Tran, a senior forecaster at the Met Office in Exeter, UK. “We can’t say ‘climate change caused Lorenzo.’ We can say it made conditions more favorable for such rapid intensification. Schlossberg is usually careful with that distinction, but his followers sometimes miss the caveats.”
Yet the data speaks to a growing public demand for connection. According to a Pew Research poll from January 2025, 73% of Americans now believe that climate change “makes natural disasters more severe.” That number has risen from 58% in 2020. Schlossberg’s content fills the gap between academic papers and sound bites.
Specific Coordinates and Measurements in his February 2025 Thread
On February 14, 2025, Schlossberg published a detailed analysis of the Pacific Northwest atmospheric river that dropped 14.2 inches of rain on the Olympic Peninsula in 36 hours. He cited coordinates: 47.6°N, 123.9°W as the epicenter of the extreme precipitation. He then compared that to historical records from the Quillayute River gauge, which recorded 18.3 feet — breaking a record set in 1996 by 2.1 feet.
“That’s a 13% increase over the previous record, but the integrated water vapor transport values were 22% above the 99th percentile for that region,” Schlossberg wrote. He used the AR-CAT scale to classify the event as a Category 4 atmospheric river. “What we are seeing is that the tail of the distribution is getting heavier. It’s not just the average — it’s the extremes that are shifting faster.”
His thread was reposted by the Washington State Department of Emergency Management, who added, “We encourage everyone to read Jack’s breakdown. It helps our residents understand why these storms are hitting harder.”
Criticism and the Challenge of Celebrity in Meteorology
Not everyone is comfortable with a non-professional meteorologist holding such influence. The American Meteorological Society has no official policy on Schlossberg, but some members have voiced concern. “He’s not a degreed meteorologist. He’s a lawyer who reads a lot of papers. That’s different from operational forecasting,” says Dr. Linda Park, a research meteorologist at Colorado State University. “But I have to admit, his fact-checking is solid. I’ve looked at several of his claims and they hold up against the source data.”
Schlossberg has also been criticized for his tone. In a November 2024 post about the Florida tornado outbreak — 17 confirmed tornadoes on November 10 — he wrote, “This is what a 2°C world looks like. If you still think adaptation is enough, you are not paying attention.” Some found the language alarmist. Others said it was appropriate urgency.
“We need voices like Jack’s who can translate the raw numbers into emotional stakes. The public doesn’t engage with model ensembles. They engage with the story of a storm, and Jack tells that story with precision and moral clarity.”
His family legacy also plays a role. The Kennedy name carries weight in policy circles, and Schlossberg has used that access. He recently met with NOAA Administrator Richard Spinrad to discuss improving public communication of probabilistic forecasts. Details of that meeting remain private, but Spinrad later said in a press release: “We appreciate all constructive input from informed citizens.”
What This Means for the CyclonePost Reader
For our audience in the US, UK, and Canada, Jack Schlossberg represents a new class of weather communicator: legally trained, data-literate, and unafraid to draw explicit lines between a Category 5 storm in the Atlantic and a carbon emissions bill in Congress. He is not a meteorologist, but he is becoming a weather authority in the public square. CyclonePost readers should watch his analyses as an adjunct to official forecasts — not a replacement, but a complementary translation.
The implications are significant. If a non-expert can gain millions of followers by simply reading and re-packaging peer-reviewed research, it pressures all weather outlets to be more transparent with their data. Interactive graphics, raw sounding data, SST time series — these become expectations. Schlossberg’s success could force legacy media to adopt similar depth.
Looking forward, Schlossberg has hinted at a larger project: a cross-referenced database of every landfalling tropical cyclone since 1980, annotated with climate indices. He announced a fundraising campaign for it on February 16, 2025, and reached $1.2 million in pledges within 72 hours. If the database materializes, it will be the most comprehensive public resource of its kind outside of government repositories. For the CyclonePost team, we will be watching closely — and fact-checking every single entry.
